- the battery pack 4 includes a housing 8 having a recess 6 defined in a surface 10 thereof. At least one battery cell 11 is enclosed within the housing 8. Coupled to the housing 8 is a handle assembly 12 configured to move between a retracted position (FIG. 1) and an extended position (FIG. 2) in which a portion of the handle assembly 12 is disposed farther from the housing 8 than in the retracted position.
- the retracted position includes the handle assembly 12 lying relatively flat against the housing 8
- the extended position includes the handle assembly 12 bowed out relative to the housing 8.
- the handle assembly 12 is coupled to the housing 8 via first and second handle mounts 16, 20 (shown in detail in FIGS.
- Each of the first handle mount 16 and the second handle mount 20 is configured to receive a portion of the handle assembly 12 therein such that the handle assembly 12 is slidable relative to the handle mounts 16, 20 between the retracted position and the extended position.
- the housing 8 is substantially rectangular in shape and includes the recess 6 defined on a widthwise spanning surface 10 thereof.
- a plane Pl containing a longitudinal axis Al of the housing 8 bisects the recess 6 and handle assembly 12. Further, the surface 10 is angled relative to a height direction of the housing 8.
- the handle assembly 12 spans the recess 6 such that the recess 6 provides easy access for a user to grasp the handle assembly 12. In some embodiments, the handle assembly 12 spans a majority of the width of the housing 8.
- the handle assembly 12 includes at least a first handle catch 24, an elongate flexible member 28, a second handle catch 32, a first fastener 36, a second fastener 40, and a grip layer 44.
- the elongate flexible member 28 is relatively bow shaped and includes a first end 48 and a second end 52.
- the first handle catch 24 is coupled to the elongate flexible member 28 proximate the first end 48, while the second handle catch 32 is coupled to the elongate flexible member 28 proximate the second end 52.
- first handle catch 24 is disposed nearer to the first end 48 than to the second end 52
- second handle catch 32 is disposed nearer to the second end 52 than to the first end 48
- the first fastener 36 couples the first handle catch 24 to the first end 48
- the second fastener 40 couples the second handle catch 32 to the second end 52.
- each of the first fastener 36 and the second fastener 40 is a rivet.
- the first and second handle catches 24, 32 may be coupled to the elongate flexible member 28 in other ways, such as through welding, adhesives, screws, bolts, or the like.
- the grip layer 44 is included in the handle assembly 12 and envelops a majority of, and in some instances all of, the elongate flexible member 28.
- the grip layer 44 may be made of a resilient, pliable, or relatively soft material compared to the remainder of the handle assembly 12, such as a polymer.
- the grip layer 44 is intended to provide added comfort and/or an ergonomic benefit to a user.
- the grip layer 44 surrounds the entirety of the elongate flexible member 28. Referring to FIG. 5, the grip layer 44 is also disposed on each of the first handle catch 24, the first fastener 36, the second handle catch 32, and the second fastener 40.
- the grip layer 44 envelops the first and second fasteners 36, 40, while being disposed on only a portion of the first and second handle catches 24, 32. Portions of the handle assembly 12, such as the elongate flexible member 28, are inserted molded within the grip layer 44 to apply the grip layer 44 to the handle assembly 12.
- the grip layer 44 may be a multi-piece clamshell separately formed from the handle assembly 12 and coupled to the handle assembly 12 during assembly. [0022] Referring now to FIGS. 3, 6, and 7, each of the first handle catch 24 and the second handle catch 32 is substantially rectangular in shape and includes an elongate slot 56 oriented along a longitudinal axis of the catch 24, 32.
- each handle catch 24, 32 includes a proximal end near which the respective fasteners 36, 40 are applied and a distal end opposite the proximal end.
- the grip layer 44 covers at least part of the proximal end.
- Each distal end is bent at an angle relative to the remainder of the handle catch 24, 32.
- the angled distal ends may provide a resting orientation of the handle assembly 12 when in the extended position. This feature promotes the handle settling into and remining in the extended position in some embodiments.
- each of the distal ends is bent at an obtuse angle to the remainder of the handle catch 24, 32.
- the handle catches 24, 32 may be made of one or more metals including, for instance, hardened steel.
- the elongate flexible member 28 is relatively bow or arc shaped and may include a strap of spring steel.
- the spring steel is arc shaped when in a relaxed state and deformable to allow the handle to give when engaged by a user to the extended state.
- the arc of the spring steel has a smaller radius in the extended state than in the retracted/relaxed state.
- the spring steel biases the elongate flexible member 28 towards the retracted position which corresponds to the relaxed state.
- Each of the handle mounts 16, 20 includes an outer body 60 defining an enclosed space 64. Extending from the outer body 60 is a post 68 having a passage 72 therein. The passage 72 is configured to receive a fastener for selectively securing the handle mount 16, 20 to the housing 8.
- Each post 68 is sized to be received within the elongated slot 56 of a respective one of the handle catches 24, 32.
- the post 68 is cylindrical; however, other geometries are contemplated herein.
- Disposed on a side surface of the handle mount 16, 20 are two rectangular notches 76.
- the surface of the mount disposed between the two rectangular notches 76 corresponds in size and shape to the elongated slot 56.
- the mounts 16, 20 may be formed from a metal, polymer, or other material.
- the posts 68 may be formed of a different, relatively harder, material than the remainder of the mounts 16, 20.
- each of the mounts 16, 20, and therefore each of the posts 68 remains in place relative to the housing 8 while the corresponding handle catch 24, 32 slidably moves relative to the post 68. Due to the elongated slots 56, each of the handle catches 24, 32 is free to slidably move relative to the corresponding post 68, while being prevented from rotating by the notches 76. Further, in pulling the handle assembly 12 away from the battery pack 4, the elongate flexible member 28 may flex into an arc shape of a smaller radius.
- each of the handle catches 24, 32 may be mounted in each of the corresponding handle mounts 16, 20 with a bias pulling the handle catches 24, 32 away from each other to return the handle assembly 12 to the retracted position.
